Experiment 6: Glitch Art

During my research I discovered an entirely new scene, and a collective of artists who create both static and moving Glitch art visuals, on and off-line. Just like Glitch audio works, there are again two different approaches to this artistic form – natural Glitch and Glitch-like. Artists will either work with naturally occurring Glitches and errors, whilst others will force the Glitch, using techniques such as databending, datamoshing, and circuitbending.

In order to create my desired aesthetic I would need to force the Glitch, instead of working with naturally occurring errors. I found that one technique in particular not only created a variety of easily achievable Glitch-like aesthetics, but it was also an approach that could be used to pre-Glitch images. Thus creating greater distortion, and further removing the original meaning and context of each users original works. I was drawn to this technique, as during the code editing process you have no idea how the code changes will affect the image outcome. The interruption in the original code disrupts the image, and the new file is the computers reinterpretation of the original, as it tries to read and overcome the broken coding.


 For this experiment I took a number of the record covers (used in other experiments) and glitched the original image via varying forms of code manipulation. In order to achieve the glitch image outputs I opened each of the images as text/edit files. In this format I cut, copied and pasted large sections of the code, deleting some and rearranging large sections. For some of these images I also employed the technique of data moshing. For this two images are opened as code and the copied and pasted code is mixed together to create new moshed version of the original images. The manipulated file is then saved and reopened as an image (jpeg). 


 These techniques are relatively quick to execute. The more code that is cut and moved the more glitched the image becomes. There were a few times during the experimentation of this technique that I glitched the images too much and the files became unreadable. I found that leaving a large section of code at the beginning and at the end of the file made it much easier for the file to be read. Removing huge chunks of code also made it much harder for the code to be read. This involved a lot of trial and error and allowed me to test the limitations of this approach. There are limits to forces glitch techniques and manipulating the code too much pushes the files to their limits.  


 The new glitched and moshed images become distorted versions of the originals. It is often easy to spot within the images where the code has been cut, which results in blank spots and pixilation. I found this technique to be extremely successfully and I was very pleased with the images I was able to create. I am currently unsure how these images will be used in the final orchestra, but I intend to feed them into MaxMSP in order to manipulate them further, and to project them digitally.


 I aim to use this technique to manipulate both digital audio and video files with the aim of creating similar outputs.

Experiment 5: Tapes

I knew that the tapes editing of audio cassettes would be the most time consuming part of the entire experiment process, and as a result decided to only edit two tapes.

Tape 1: I started by carefully pulling the tape out of the cassette, and cut a large section of the tape away. I then cut a small piece of clear tape (around 1-2cm in length) and taped the two ends together, ensuring that the tape did not twist in the process. I repeated this process over and over, randomly cutting out varying amounts of tape, whilst trying to vary the distance between the joins. This process was extremely intricate and very time consuming. It took almost two hours to complete the entire tape. On play back I notices that I had left large portions of tape untouched, allowing the tape to play the original audio. As soon as the head reached a piece of tape that had been taped together the audio would either speed up or slow, creating an interesting whirling effect to the audio. Whilst the playback was extremely successful, and the technique create some interesting and unusual audio outputs, I feel that the output could have been improved by a great frequency of joins, and leaving less tape in-between the joins.   




Tape 2: Having tested out tape 1, I decide to cut the second tape more often, leaving smaller amounts of tape in-between the original tape. I believed that this would improve the glitch output, and would result in a unique sound. Again, this technique took around two hours. Whilst my technique had certainly improved, I was cutting more, and as a result creating more joins. I tried to play the finished cassette, but there were some issues with playback. It would seem that the increased amounts of clear tape made it difficult for the head to read it, resulting in the tape getting stuck. Whilst I assumed that the addition of more tape and cut would improve the glitch, it instead pushed the format and player to its limits, making it difficult for the tape to be played and heard.


In order to incorporate this technique into the orchestra, I will need some further testing. I think it is possible to find a happy medium, where the original is still heavily glitched and still playable. My only concern is this technique is extremely time consuming.

Experiment 4: Painted, Scratched & Taped CDs

The next stage of audio experimentation featured a number of CD manipulation techniques – Painted, Scratched and Taped.

I used the following materials to achieve my desired results –
- CDs
- Acrylic paint
- Small paintbrush
- Clear tape
- A sharp compass 

Scratched CDs (1): I started by using the compass to lightly scratch vertical lines (1 inch in length) randomly around the CD. As I hadn’t used this technique before, and because there is little detail regarding CD scratching techniques, I decided to use a light scratch to see the effects.
Result: Normal playback - no change in sound.
CD: Steve Thomas – Trade Disc 1


Scratched CDs (2): Again, using the compass I decided to test the effects of deeper scratches / horizontal lines (1.5 inches in length) randomly around the CD.  
Result: Normal playback with skipping and glitching.
CD: Tony De Vit – Trade


Coded Scratch: I used a CD single (Gandam Style) for the next scratch based experiment. I found a digital copy of the song and transferred it into code, and printed out the first page. I then took this code and scratched (using the compass) as much of if I could fit onto the CD with a medium amount of pressure.
Result: Normal playback with mild skipping / glitching effects.
CD: Psy – Gangnam Style


Taped CDs (1): For this experiment I took three long pieces of clear tape and placed them on the CD, making sure that the pieces reached and overlapped the edge of the disc. This technique is similar to that used on the vinyl experiments, as I was interested to see if the audio output results were similar.
Results: CD – unreadable.
CD: Rock and Roll Origins – Homemade CD


Taped CDs (2): Next, I took small sections of tape (approx. 1.5 inches in length) and randomly placed them around the disc ensuring that they were fully stuck down. I wanted to use an alternative technique to test out how different amounts of tape would effect the playback.
Results: Skipping effects.
CD: Janis Joplin – Pearl


 Painted CDs (1): For this CD I used basic white acrylic paint and a small brush to pain random patterns onto the disc. To test the effects of smaller randomised paint marks.
Results: No change in playback.
CD: Madonna – Music


Painted CDs (2): I wanted to use larger amounts of paint for this experiment to test how more paint would change the playback. I added blobs of paint that looked like black clouds; to ensure a greater surface area was covered with paint.
Results: Glitched and skipping effects.
CD: Various Artists – Simply Swing


Overall: None of these approaches were particularly time consuming, and most took just a few minutes to complete. However, it was surprising to find that whilst some of the effects heavily affected the sound, others had little to no effects on the outputted sound. I was certain that all approaches would have an effect, and was extremely surprised with the results.  

I found that the three most successful approaches were –
Deep Scratching
Painted (Black large sections)
Tape (Smaller sections of tape)
I intend to use all of these techniques in the glitch orchestra, as they produced the most interesting audio outputs.

Experiment 3: Changing the Needle

Whilst the broken needle of my tester turntable was an annoying set back, it did however allow me the opportunity to test out another planned experiment – replacement needles. This technique requires a change in the physical player rather than the audio / visual format, which made this experiment a little different from all the other tests I had planned. The changing of the needle was again chosen to test how different material could potentially change the outputted sound. During my research into Knizak’s work I discovered various needle replacement techniques that he and other Glitch artists have employed, using a variety of replacements such as toothpicks and shape metal implements. I decided to try both these and a few techniques of my own.
I found some basic instructions here - followed these, and set about making my own replacement needle record player.


Needle (a): Paper Cone
To kick off with I took an A4 piece of paper and rolled it into a cone shape with a sharp point. I then borrowed a sewing needle from my girlfriend and poked this through the point, securing it there with clear tape. I then taped the cone and needle to the arm and started the record. This was extremely wobbly and didn’t work as well as I had would have expected. At one point I held the needle in place to ensure that it was in full contact with the grooves, and it began to pick up more sound. The cone was working as an amplifier, yet the sound was extremely quiet. As the cone was so unsteady, needed my help to stay in place, and the fact that the output was so low makes this technique an unsuitable addition to the glitch orchestra. Perhaps a thicker needle, thicker card, a larger cone and stronger tape may have made this a little more successful. I will not be exploring this option any as I don’t feel that the changes will make a great deal of difference to the outputted sound.







Needle (b): Cocktail Stick
I started this process by snapping a cocktail stick into two pieces and securely taped one end of the stick to the needle arm. I placed an undamaged record onto the turntable, as I wanted to be able to gauge the full effects of the needle. Whilst this was an extremely simple way to create a new needle, there were some issues with weighting. Because of the size of the new needle the balance became off, and it was difficult to keep the needle down on the record. The needle worked when I held it into place and added pressure, but the outputted sound was muffled and crackly. The thickness of the needle made it difficult for it to find a groove, causing the needle to constantly move around. When I tired playing the needle without the extra weight I provided by holding it in place the needle slide across the record to the end of the disc, and created no audio output.


Needle (c): Plastic Knife
For this experiment I used a disposable knife, which I again securely taped to the arm of the player. Again, there were immediate issues with weight, and the knife only worked when I held it into place. When I tried the knife without assistance it couldn’t find a groove as it was too thick, and jumped to the end of the disc without creating an audio output. The results were very close to those produced with the cocktail stick.


Overall: All three of the techniques I tried did not produce the expected results, and therefore will not be used as part of the final orchestra. However, in the future I would like to try this technique again, using a variety of different techniques. I feel that there is a great deal of experimentation needed with this approach, and unfortunately, due to limited testing time, I cannot dedicate any further time to this technique.

Experiment 2: Breaking Records

This is the second set of experiments that involve the manipulation of vinyl records. This process involves the snapping/cutting of various sized discs into multiple pieces and then taping them together with piece from other disc. This technique originally featured in Knizak’s piece “Broken Music”. In his works Knizak snapped/cut his discs into halves. I decided to build on this approach, and incorporated 1/3 and 1/4 in order to create a variety of new sounds.   

Snapped in ½
For this initial experiment I began by cutting two different 12” singles in half. Using a cut and paste technique in order to create a “mash up” of the two songs, which would result in an entirely new composition. Unfortunately, due to the larger size of the discs the two halves would not stay together and the two pieces continually fell apart on play back. I decided to try this approach again, and instead used 7” singles, as I thought it was more likely that the two halves would remain stuck together. I began by trying to break the two records in half. This proved to be extremely difficult as snapping did not result in a clean break, which would make taping the two halves together difficult. I decided to cut the records with scissors and this technique proved to be far more effective and created a clean cut down the middle of the disc. The two precisely cut halves made it far easier to reassemble the discs with tape. Initially, I was going to use glue as an alternative technique to the tape, but quickly found that tape was the better solution, as the tape helped to bridge the any gaps between the two halves. I decided to use records from different musical genres, as I believed that this would help to produce an interesting result. I chose to use Breed 77 “World’s on Fire” (heavy metal) and Michael Jackson “Thriller” (pop). I set up my camera and placed the record onto the turntable, and was surprised by the results. The output sounded like two different songs were being badly mixed together. As before, the needle slid across the tape that was holding the two halves together and jumped to find a groove. The sound would cut in and out as the needle jumped between the two halves.


I believe that this was an extremely successful experiment, and an effective way to glitch audio. The audio output was unexpected, and is certainly a technique that I intend to use again. I would like to experiment with other different halves, but I am extremely please with the way these two songs work together to create an entirely new piece.   

Snapped in 1/3
This follows on from the previous broken and reassembled record experiment. However, this time I wanted to find out how the shape of the broken sections affected the audio output. For this experiment I took the following 7” singles, cut and pasted them together - Breed 77 “World’s on Fire”, Phil Collins’ “A groovy kind of love”, and Elaine Page with Barbra Dickson’s “I know him so well”. Both Collins’ and Paige’s records where cut into quarters and taped together with the half of the Breed 77 record. Resulting in a 1/2 and 2 x 1/4’s. 


Again the record was placed onto the turntable and the results where recorded. I found the result were very similar to the broken halves as the needle skipped over the taped sections and cut between the three songs.
Unfortunately, this method was less effective than the 1/2’s as the one half of the record dominated the output, whilst the 2 x 1/4’s were lost. During the playback of this disc took its toll on my turntable causing the needle to break off. This unexpected turn has set me back, as I wanted to test all of the records on my experimental record player. I don’t want to use any of the untested experiments on my main record players, as I worry that they will cause damage. In order to continue I will need to secure another test record player with a cartridge needle. In the meantime, I intend to continue to create new discs ready for the new player.

Snapped in ¼
Fortunately, I was able to pick up another record player, allowing me to finish off the record based portion of my experiments. This time I decided to use equal quarters, and used the following discs - Michael Jackson “Thriller”, Phil Collins’ “A groovy kind of love”, Elaine Page with Barbra Dickson’s “I know him so well” and Spunge’s “Roots”. Due to the brittle nature of the discs it was extremely difficult to ensure that all of the four quarters were clean cuts. This resulted in some overlapping of the vinyl, which I assumed would be difficult for the needle to deal with. I place the disc on the turntable and dropped the needle, and as soon as I did it jumped off straight away. I tried again by placing the needle neared the centre of the disc. The needle stayed on for longer, but it jumped off after just a few seconds. The smaller the piece the more difficult they are to cut and paste back together. As it is difficult to ensure the clean cuts of the disc, it causes overlapping. The needle is just too delicate and cannot move across overlapped vinyl. I don’t think the smaller cut will work for my final project, as the playback time is simply to unpredictable and short.


Overall (Snapped 1/2, 1/3 & 1/4):
Overall I feel that these techniques are an effective way of creating new “mash up” versions of the songs. Whilst the breaking and reassembling of the discs produces a unique result, I am cautious that the record playback time is just too short in order to be effective. The unpredictability of the needle often results in the arm jumping to the end of the record. Further experiments will need to take place to measure if another cutting technique will produce more effective playback results.
